    My mate opened it thinking it was actual protein and the onesie just shot out. worth it for that alone honestly but the onesie itself is proper cosy too.

    ok I was skeptical about but it doesn't look cheap at all. the detail down the legs is really nice and the zip isn't flimsy like other ones I've bought. living in this now.

    Commonly asked

    Questions

    Is it actually warm?

    Yes. It’s thick double-layer sherpa. Wear it on the couch, at the game, or out on a cold night.

    Do the muscles go flat in the wash?

    No. The muscles are stitched padding, not a print. Machine wash cold, inside out, and hang to dry.

    Does it run big or small?

    It's designed to be roomy not skin tight. If you're between sizes go with your normal one, it's already got a relaxed fit.

    Is there actually protein in the tub?

    0g. Just gains.

    Can I wear it outside?

    People wear them to the gym, the store, college and the Christmas party. That’s kind of the point.

     
     
    • Morning Brew Hit Different

      "stood outside in the rain with a coffee and didn't feel a thing. the sherpa is genuinely warm not just soft for the sake of it. hood up, zip up, I could stand out here all day"

      — Megan R. Ohio

    • My Girlfriend Won't Stop Taking Photos of Me

      "I was just making a cup of tea and she pulled her phone out again. the print detail up close is mad though I'll give her that. the griffins on the chest look even better in person than onlineee times. Our manager ended up with it and it's been dancing on her desk every morning since. Nobody gets any work done at 9am now."

      — Tyler B. Texas

    • Gaming Uniform Now

      "my girlfriend took this from the door and I didn't even know. I wear it every single session now. it's warm without being sweaty and the back print looks hard apparently. her words not mine"
